The seismic instrument recorded 383 volcano-tectonic earthquakes over the past 24 hours including 238 periods of the elevated amplitude volcanic tremor that lasted 1-12 minutes. This indicates elevated fluid movements of gas, water and possibly magma under the surface.
In addition, sulfur dioxide (SO2) emissions increased rapidly to a 1886 tonnes/day on 12 April as emissions of steam-laden plumes rose approx. 300 meters above the fumarolic vents. For comparison, SO2 emissions reached to a 799 tonnes/day on 9 April.
The Main Crater Lake temperature reached to a 71.8°C with a pH of 1.59 on 4 March caused by volcanic gas reaching the shallow hydrothermal system that feeds into the lake accompanied by degassing.
